Axle-nut lock.



T onlluuih'afit. magi concerns: 13e 1t known that I, ROBERT G. ROBERTS, citizen of'the United States, residing at North Y mhill, 'in the county of Yamhill and Stat-'e I Oregon, have invented' certain new and useful Improvements; in Axle-Nut' Locks, of which the following is a specification.

'The object of'thisinvention isl a simple,. durable and eilicient construction of nut lock which 1s arranged to automatically lock an .lxle 4nut upon the axle so las to )revent' any further tig iteningmovement oft 1e nut upon the axle, and also to prev'en the accidental disengagement of the former from the latter.

' Viiith this and other objects in view that will more fully appear as the description p ro- Y knowledge of the det-ailsof construction reference is to be had to the following descri tion'and vaccompanying drawing, in whic i:

Figure 1 is a perspective view of my improved nut lock, showing it applied; Fig. 2 1s a section on the line `2-'2 of Fig. 1, showing in dotted lines a wrench applied to the nut and springing the keeperout of position; and,

` Fig. 3 is a perspective view showing the nut and keeper in juxtaposition.

Correspondlng and hke parts are referred y to in the following descriptlon and indicated in all the views of the drawing, by the same reference characters.

Referring to the drawing, the numeral 1 designates 'an axle which may be of any desired construction or design, except that it is threaded near its end, as indicatelat 2, and

` is formed in such end with a radially extend'- ing recess 3.

Anaxle nut 4'is designed tobe mounted upon the axle 1 and engaged with the threads 2 thereof,- and is formed in its exterior face with a semi-circular recess 5 that communicates 'with the central oiening extendin Irv through the nut, said nut e'mg also formed with a groove 6 leading from one end of the recess and extending radially outward therefrom, as shown.4 A substantially semi-cir- AxLE-NUT noci;

cular spring kee er 7 is normally'i'eceived in the 'recess 5, an '1s rigidly secured at one end therein, said keeper being formed at its other 'end witha laterally enlarged head 8 that is spring-pressed so' as to normally tit in the groove 6 with its extremities projecting'im' wardly and outwardly beyond the nut, as shown. v In the practical use of my improvedfnut lock, the axle. nut 4 is mounted upon the axle 1 and engaged with the threads 2 thereof. Upon the advancement of the nut, the inner extremity of the head'S abuts against theend of Vthe axle, which results in the head 8 being sprung out of the groove 6 until the nut subsequently assumes such a positionl that the groove (S thereof is in alinement with the recess 3, whereupon the head S-returns to its normal position in the groove 6, with its innerextremity fitting in the `recess 3 and holding the nut rigidly upon the axle with its outer face substantially flush with the end thereof. In removing the nut 4 from the axle, a wrench or similar instrument is engaged with the same, and is rocked so that one o f the jaws thereof will bear against the outer extremity of the head S and s ringthelatter out of the groove 6 and the c iannel 3, thus unlocking the nut and permittinC it to be removed from the axle m the ordinary manner. Y

From the above description, in connection with the' accompanying drawing,`it will be a i )arent that I have rovided a sim le,

l 1l P P durah e and efficient construction of axle nut lock which is arranged to effectual] secure the axle nut to the axle and permit the nut to be readily removed from the latter when such is desired, and which consists 0f comparatively few )arts that may be easily and cheaply manu 'actured and quickly Aassembled.'

Having thus described the invention, what Iclaimisz' i The combination with a threaded element formed in its end with a radially extending recessfof a nut adapted to he screwed on such element and formed in its face with a circumferential recess and with a radially extending groove that communicates with one ceSs in the nut and formed at 'its other or l In testimony whereof I afix my signature free @Hd 'fh al mlgularly (h5 OSed headlhag in presence of two Witnesses.

V i ro'ects evon tle inner anT outer wa s o h'ejnut and is arranged to ride upon the end ROBERT G' ROBERTS' [L' s'] 5 of the threded element-'and snap into the fitnesseszl irecess therein and into the groove, when the T. MCLAUGHLIN,
